RO/DI output

I just hooked up a 6 stage ro/di unit I purchased on an

[hr]
site. Although I dont know what my water pressure is, I assume it's sufficient because I'm getting water both from the good end as well as the rejection hose. My question is, on average what is the ratio between rejected and clean water? Just estimates would be fine not looking to break it down to ozs or anything.
Thanks,
Tom

pressure and temp both make all the difference but the normall out put is around 25% good 75% rejected.
temp should be 67 and pressure should be 60 to 70 psi

After a couple of hours running it measures about 3:1 waste to pure water. Maybe a little higher on the pure side.
